Background: Real-world data on the molecular epidemiology of EGFR resistance mutations at or after progression with first- or second-generation EGFR-TKIs in patients with advanced NSCLC are lacking. Methods: This ongoing observational study was carried out by 23 hospital-based physicians in Greece. The decision to perform Cobas® EGFR Mutation Test v2 in tissue and/or plasma at disease progression was made before enrollment. For patients with negative/inconclusive T790M plasma-based results, tissue re-biopsy could be performed. Results: Ninety-six (96) eligible patients were consecutively enrolled (median age: 67.8 years) between July-2017 and September-2019. Of the patients, 98% were tested upon progression using plasma and 2% using tissue/cytology biopsy. The T790M mutation was detected in 16.0% of liquid biopsies. Tissue re-biopsy was performed in 22.8% of patients with a T790M-negative plasma result. In total, the T790M positivity rate was 21.9%, not differing between patients on first- or second-generation EGFR-TKI. Higher (≥2) ECOG performance status and longer (≥10 months) time to disease progression following EGFR-TKI treatment initiation were associated with T790M positivity. Conclusions: Results from plasma/tissue-cytology samples in a real-world setting, yielded a T790M positivity rate lower than previous reports. Fewer than one in four patients with negative plasma-based testing underwent tissue re-biopsy, indicating the challenges in routine care settings.

e21641 Background: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are the gold standard 1st line strategy for non-small-cell lung cancer (NSCLC) patients with activating EGFR mutations (EGFRm), associated with improved survival outcomes and quality of life compared to chemotherapy. Despite the high response rate with first- and second- generation TKIs, most patients develop resistance to treatment and progress. The acquisition of T790M mutation in exon 20 is considered the most common resistance mechanism. This study aims to investigate the molecular epidemiology of EGFR resistance mutations, focusing on T790M in EGFRm NSCLC patients treated with TKIs. Methods: The study included patients with locally advanced/metastatic EGFRm NSCLC who have progressed on or after 1st line treatment with first- or second- generation TKI. Samples either from plasma-based liquid biopsy and/or tissue re-biopsy were analysed using the Cobas EGFR Mutation Test v2. All patients signed informed consent and were enrolled between July 2017 and September 2019. Statistical analyses were performed using SAS software, Version 9.4. Results: Ninety-six eligible patients were enrolled. At the time of progression, T790M mutation was detected in 16.7%of the patients using plasma-based liquid biopsies. Among patients with negative T790M result, in plasma, tissue re-biopsy was performed in 22,7% with evaluable/valid results in 72.2% of them. T790M mutation was identified in 38.5% of re-biopsy samples. According to Cobas EGFR Mutation test results (combined plasma and tissue), T790M mutation was identified in 21.9% of the patients. Of T790M-positive patients 42.9% had previously received first and 57.1% second generation EGFR-TKI. Conclusions: Results from this study in real world clinical setting in Greece, show that EGFR-T790M acquired resistance positivity rate in plasma is lower compared to previous reports. Moreover, these data underline the challenges of implementing precision medicine using tissue re-biopsy in advanced/metastatic NSCLC. Clinical trial information: D133FR00126. [Table: see text]

e23101 Background: Epidermal growth factor receptor (EGFR) mutation is the most important factor for determining the treatment strategy for non-small-cell lung cancers (NSCLCs). Currently, two methods (cobas and Scorpion ARMS) have been approved as companion diagnostics for using EGFR tyrosine kinase inhibitor (TKI). Although there are some differences in the spectrums and sensitivities for detecting EGFRmutations such as exon 19 deletions (ex19del), L858R and T790M mutations, the extent of the differences affecting clinical practice is unclear. Methods: All patients with NSCLC who underwent EGFR mutation tests and treated at our hospital from February 2014 to February 2016 were enrolled. To detect EGFR mutations, the Scorpion ARMS (S) method was used from 2014 to 2015 and thecobasEGFR Mutation Test (C) from 2015 to 2016. We retrospectively investigated the detection rate of each EGFRmutation type and compared the rates between the two methods. Results: A total of 1,287 patients were enrolled. To detect EGFR mutations, 627 patients were tested by the S method and 660 by the C method, respectively. Of 1287 patients, 910 patients underwent initial biopsy, whereas 121 patients underwent re-biopsy after EGFR-TKI failure. EGFRmutations were detected in 130 of 418 (31.1%) patients and 153 of 492 (31.1%) patients by the S and C methods, respectively in the initial biopsy (P = 0.982). However, the detection rate of ex19del was slightly lower in the S method (12.6%) than in the C method (16.3%) (P = 0.105). Conversely, the detection rate of L858R was lower in the C method (13.8%) than in the S method (16.7%), but the difference was not significant (P = 0.252). De novo T790M was detected in one (0.2%) patient by the S method and in none by the C method. In re-biopsy after EGFR-TKI failure, the detection rates of T790M were as follows: 19 of 55 patients (34.5%) by the S method and 20 of 66 (30.3%) by the C method (P = 0.619). Conclusions: The different spectrums and sensitivities of EGFR mutations between the S and C methods were observed; however, they did not significantly affect clinical practice.

7045 Background: We previously reported efficacy and safety of cisplatin-docetaxel and concurrent thoracic radiotherapy (TRT) for LA-NSCLC (Segawa Y and Kiura K. JCO 2010). However, its cure rate remains unsatisfied, and further improvement in the treatment outcome is strongly warranted. Recently, systemic chemotherapy has been individualized by intensive anti-cancer researches through the discovery of certain molecular targets in the metastatic NSCLC. Especially, gefitinib, EGFR tyrosine kinase inhibitor, is quite active and now one of the standard chemotherapy for untreated metastatic EGFR-mutant NSCLC (Maemondo M and Inoue A. NEJM 2010). Even in the locally advanced setting, approximately 30% of Japanese NSCLC patients possess EGFR-mutant tumors. Given all of these backgrounds, investigation on the role of adding gefitinib monotherapy to the standard concurrent chemoradiotherapy might cause a new paradigm shift in this setting. Methods: Patients have to meet the following eligibility criteria: LA-NSCLC; active tumor EGFR mutations (exons 19 and 21) but without 790M; measurable lesions; performance status (PS) of 0 or 1; age < 75 years; and V20 ≤ 35%. The primary endpoint is set as 2-year progression-free survival (PFS) rate; assuming that 75% in eligible patients would indicate potential usefulness, whereas 60% would be the lower limit of interest (α = 0.05, ß = 0.20), the estimated accrual number is 46 patients. The secondary endpoint includes toxicity, response rate and overall survival. Patients will receive the induction treatment, specified as gefitinib monotherapy (250 mg/body) for 8 weeks. Patients who have not progressed during the induction therapy will receive cisplatin and docetaxel (40 mg/m2; days 1, 8, 29, 36, each) and concurrent three-dimensional conformal TRT (2-Gy, single, daily fractions for 5 consecutive days each week to provide a total dose of 60 Gy). Enrollment began in 2010, and will complete by 2015. UMIN registration number of 000005086.

First-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) is a standard treatment for patients with activating EGFR mutations. Six randomized studies have demonstrated consistent improvement in tumor response rate and progression-free survival over platinum-based combination chemotherapy. The only reason to consider EGFR TKI as second-line therapy is that none of the six comparative studies has shown improvement in overall survival, which can be explained by the high proportion of patients from the chemotherapy arm crossing over to the EGFR TKI arm on progression. It is true that patients with EGFR mutations may benefit from second-line EGFR TKI therapy, but we cannot conclude that the benefit is either equal to or inferior to first-line EGFR TKI therapy. To date, there are no direct comparative data between first- and second-line EGFR TKI in patients with activating EGFR mutations. Tumor response rates to second-line EGFR TKI have been inconsistent, which could potentially be explained by the impact of first-line chemotherapy on the abundance of tumor cells with activating EGFR mutations. However, numerous arguments, including assurance on drug exposure, improvement in quality of life, better tolerance by patients with poor performance status, and deferral of whole-brain radiation therapy for patients with brain metastasis, support the general application of first-line EGFR TKI.

Purpose An American Society of Clinical Oncology (ASCO) provisional clinical opinion (PCO) offers timely clinical direction to ASCO's membership following publication or presentation of potentially practice-changing data from major studies. This PCO addresses the clinical utility of using epidermal growth factor receptor (EGFR) mutation testing for patients with advanced non–small-cell lung cancer (NSCLC) to predict the benefit of taking a first-line EGFR tyrosine kinase inhibitor (TKI). Clinical Context Patients with EGFR-mutated NSCLC have a significantly higher rate of partial responses to the EGFR TKIs gefitinib and erlotinib. In the United States, approximately 15% of patients with adenocarcinoma of the lung harbor activating EGFR mutations. EGFR mutation testing is widespread at academic medical centers and in some locales in community practice. As of yet, there is no evidence of an overall survival (OS) benefit from selecting treatment based on performing this testing. Recent Data One large phase III trial (the Iressa Pan-Asia Study [IPASS] trial), three smaller phase III randomized controlled trials using progression-free survival as the primary end point, and one small phase III trial with OS as the primary end point, all involving first-line EGFR TKIs and chemotherapy doublets, form the basis of this PCO. Provisional Clinical Opinion On the basis of the results of five phase III randomized controlled trials, patients with NSCLC who are being considered for first-line therapy with an EGFR TKI (patients who have not previously received chemotherapy or an EGFR TKI) should have their tumor tested for EGFR mutations to determine whether an EGFR TKI or chemotherapy is the appropriate first-line therapy. NOTE. ASCO's provisional clinical opinions (PCOs) reflect expert consensus based on clinical evidence and literature available at the time they are written and are intended to assist physicians in clinical decision making and identify questions and settings for further research. Because of the rapid flow of scientific information in oncology, new evidence may have emerged since the time a PCO was submitted for publication. PCOs are not continually updated and may not reflect the most recent evidence. PCOs cannot account for individual variation among patients and cannot be considered inclusive of all proper methods of care or exclusive of other treatments. It is the responsibility of the treating physician or other health care provider, relying on independent experience and knowledge of the patient, to determine the best course of treatment for the patient. Accordingly, adherence to any PCO is voluntary, with the ultimate determination regarding its application to be made by the physician in light of each patient's individual circumstances. ASCO PCOs describe the use of procedures and therapies in clinical practice and cannot be assumed to apply to the use of these interventions in the context of clinical trials. ASCO assumes no responsibility for any injury or damage to persons or property arising out of or related to any use of ASCO's PCOs, or for any errors or omissions.

e20518 Background: Compared with the first generation of EGFR-TKI, Afatinib has a broader spectrum of activity and can better inhibit tumor growth. At present, the therapeutic effects of Afatinib varies on patients with different EGFR mutations and studies on the mechanism of acquired Afatinib resistance are limited. The aim of this study was to evaluate the efficacy and safety of Afatinib in the treatment of EGFR-mutation NSCLC who hadn’t received EGFR-TKI in the past. Methods: 88 patients with advanced NSCLC who had EGFR mutations were enrolled and given oral 40 mg Afatinib daily until disease progression or adverse events that could not be handled by dosage reduction. Efficacy and safety in different subgroups were analyzed. Results: Among 88 patients, the common mutation rate of EGFR was 79.5%, and the rare mutation rate was 20.5%. The objective remission rate (ORR) was 54.5%, and the disease control rate (DCR) was 92.0%. The median progression-free survival (PFS) was 14.2 months (95% CI 11.4-18.5), 27 patients (30.7%) continued Afatinib treatment after tumor progression, and the median time to progression of clinical symptoms (TTSP) was 16.3 months (95% CI 12.7-19.3). A total of 13 patients (14.8%) reduced Afatinib dosage of due to adverse events. Subgroup analysis showed that Afatinib had better effect on patients harboring common EGFR mutation but not exon 20 mutation, and was not affected by brain metastasis, dosage and lines of therapy. Among patients who progressed on Afatinib, 65.4% harbored T790M mutation. Most T790M patients received the third generation EGFR-TKI including AZD9291 and oxetinib treatment. The most common adverse reactions were diarrhea, rash, paronychia and stomatitis. Conclusions: Afatinib showed good efficacy and tolerance in advanced NSCLC patients with EGFR mutations. Continuation of Afatinib treatment after cancer progression could delay the progression of disease symptoms. The third generation EGFR-TKI could become a treatment option after Afatinib resistance. These findings reflected the real-world clinical practice of Afatinib.

9020 Background: In the Phase III FLAURA trial (NCT02296125), osimertinib, a third generation EGFR-TKI, showed superior efficacy to comparator EGFR-TKIs as first line treatment for EGFR mutation-positive (EGFRm) advanced NSCLC. In an exploratory analysis, we investigated clinical outcomes associated with detection of plasma EGFRm at 3 or 6 weeks (wks) after start of treatment. Methods: Treatment-naïve patients (pts) with EGFRm (ex19del or L858R) locally advanced or metastatic NSCLC were randomized 1:1 to receive osimertinib 80 mg once daily (QD) or comparator EGFR-TKIs (gefitinib 250 mg QD or erlotinib 150 mg QD). Plasma EGFR mutation analysis was conducted at baseline (BL), wks 3 and 6 by droplet digital PCR. Clearance was defined as undetectable levels of EGFRm in ctDNA at wks 3/6, where they were detectable at BL. Progression-free survival (PFS) was investigated based on early clearance of EGFRm. Results: In total 489/556 (88%) pts (osimertinib: 244/279; comparator: 245/277) had evaluable ctDNA at BL and wks 3/6. Of these, 342/489 (70%; osimertinib: 168/244; comparator: 174/245) had detectable BL EGFRm and were included in this analysis. See table. Conclusions: Clearance of plasma EGFRm after 3/6 wks of EGFR-TKI therapy was associated with a numerical improvement in PFS. The efficacy of osimertinib was superior to comparator EGFR-TKIs regardless of clearance status. Clinical trial information: NCT02296125. [Table: see text]

e20638 Background: Anti-angiogenic agents have been reported to have clinical activity for NSCLC harboring EGFR mutation (mutEGFR) with/without EGFR Tyrosine kinase inhibitor (TKI). We report clinical outcomes of nintedanib plus docetaxel for refractory NSCLC patients conducted by virtue of Korean NPU program. Methods: Patients with NSCLC were eligible if they failed at least one prior systemic treatment. Docetaxel was administered with 75 or 60mg/m2 on D1 or 37.5mg/m2 on D1, D8 every 3 weeks plus nintedanib 200mg orally twice daily. Nintedanib treatment was continued until disease progression or unacceptable toxicity after 4-6 cycles of combination therapy. Results: Of 62 patients enrolled, 23 patients had activating EGFR mutations (14 in exon19 deletion, 7 exon21 L858R/L861Q, 1 exon20 duplication, and 1 in both exon19 deletion and exon20 T790M) and progressed during prior EGFR-TKI treatment. Of 23 patients, 22 had progressed during or after platinum doublet chemotherapy. Only for 2 patients, EGFR mutation status was unknown. The majority of patients were heavily pretreated, with 43.7% received nintedanib plus docetaxel as ≥ 4th line therapy. 4 patients had prior bevacizumab treatment. Objective response rate (ORR) was 22.9%. Median PFS and OS were 3.9 months (95% CI 3.1-4.6) and 9.5 months (95% CI 5.3-13.7), respectively. Depending on EGFR mutation status, ORR in mutEGFR group was higher than wtEGFR group (30.4% vs 20%, p= 0.50) and median PFS in mutEGFR group was significantly longer than wtEGFR group (6.1 vs 3.3 months, p= 0.008). No treatment related death was reported. Common grade 3/4 adverse events were neutropenia (58.3%) and reversible elevated liver enzyme (18.8%). Conclusions: Taken together, nintedanib plus docetaxel showed meaningful clinical activity with good tolerability for refractory NSCLC patients. Our data suggest that this combination may be a recommendable regimen for EGFR-TKI-resistant mutEGFR NSCLC.
